How to improve the filtration performance of a filter?
2023-12-20
To ensure that the filtered water quality meets the standards for drinking water quality, polymer coagulants such as polyacrylamide or activated silica can also be added before the raw water enters the filter. Direct filtration of raw water eliminates the need for sedimentation or clarification processes, simplifies the treatment process, and saves investment. Using double-layer filter media and multi-layer filter media for direct filtration, the same as ordinary double-layer filter media or multi-layer filter media filters. But the composition and thickness of the filter layer should be reasonably selected according to the raw water quality, and the filtration rate should be low, generally around 5m/h.
